SierraNegra-GTK

Actual version from repository (using it).
I'm on Gnome 3.36 and there are some not-fitting colors on the gnome-shell theme because they changed something. So for the gnome-shell theme, I'm using a slighted modified version of Flat Remix Miami (attached below - It's a different style, maybe the dropdowns doesn't fit very well, but I liked in my setup, meanwhile).

Adjust some border colors; better look on some apps

Note that this is the final release with colors as it can saw in Reddit and Imgur album.
Now I'm doing changes to get an overall look bit less saturated. So if you use newer files than this one, you can find some differences in terms of colors and shadows.

This version should look like in this screenshot.
